8 Claims.

This invention relates to improvements in liquid registering devices.

It is a primary object of this invention to provide a new and improvedform of a liquid registering meter in which the operative life of thedevice has been prolonged by reorganization and redesign of the parts.

More specifically it is an object to protect from exposure to the liquidpassing through the meter those portions of the device subject tocorrosion through electrolytic or alkaline action.

It is a still further object to protect the working parts of the meter,particularly the gear train and spindle disc assembly, from impeding andabrasive actions of foreignparticles such as sand and grit, through theuse of a tight tting gear train base and a sand ring cylinder separatingsuch parts from the liquid carrying such. sediment. It is a furtherobject of the invention to provide a novel gear train mounting involvingthe elimination of some separate frame elements and the relocation ofall necessary bolts in protected'locations. It is another object toprovide a mounting and locking means for the metering disc chamber, ywhereby the discharge opening in said chamber can be positivelypositioned in registry with the discharge port'in the meter housing. Inthe drawings:

Figure 1 is a vertical cross section of a water meter showing anembodiment of my invention. Figure`2 is a plan view of the gear framebase element. Figure 3 is a horizontal cross section taken on the line3-3 of Figure 1.

Figure 4 is a plan view showing the interior ofl the meter bottom.

Like parts are identied throughout the several views by the samereference characters.

Referring specifically to Figure 1, it will be noted that I show manyconventional features of a commonly used wobble type disc liquidregister including the register case IIJ, meter housing 4'5 top Il,meter housing bottom I2, liquid entry port I3, liquid discharge'port I4,disc chamberv I5, disc and spindle unitv I6, driving pawl I1 and y driveshaft I8.

Disc chamber I5 is provided below its discharge' y5o port 22 with anarcuately formed externally bevelled ear 25, Fig. '.1, capable of beingreceived in a similarly disposed complementarily formed and bevelledlarcuate clamp 'channel 28 in the meter housing bottom I2. LevellingsupportsV 21 for l55 the'chamber I5 are provided on thebottom I2,

.ing chamber I5.

- conically tapered thrust member 58 whereby an (Cl. 'I3-258) Fig. 4, atpredetermined points. These supports 21 with the clamp ear 25 and thechannel 28 position the chamber I 5 at a proper level so that itsopening 22 registers with the discharge port I4. Pressure by the top ofthe meter case assembly, in assembled relation, exerted on the top ofthe chamber I5, tends to clamp the ange 25 of the `chamber I5 inposition in the channel 28. The bevelled portions of the flange 25 andthe channel 2B tend to force the chamber I5 later- 10 ally of the bottomI2 into closer contact with the outlet wall of the meter bottom I2,thusy producing what is in effect a coacting bearing relation betweenthe outlet wall of the bottom I2 and the coacting surface of the chamberI5, 15 when the aforementioned pressure is applied upon the chamber I5.The required pressure may be developed by the cap screws 51 threadedinto the ears 58 of the base and engaging the correspending lugs 59 atthe top of the casing, one 20 suchlug being shown in Fig. 4 and thegeneral n organization in this regard being conventional. The screen 30,best shown in Figure 3, has obliquely formed spacing ends 3| contactingthe wall of the chamber I5 about which it is disposed. 25

Screen 30 is substantially of the same vertical height as the chamberI5,land it is mounted to contact the upper and lower wall portionof thebottom I2, thus forcing any liquid entering by way of port I3 to passtherethrough before entcr- 30 The meter housing top II has a partitionapertured at 5I to receive the neck 52 of the top frame member 35 of thegear train assembly I9. Member 35 is secured in position by a lock n'ut35 49 threaded to the neck 52. Packing washers 41 and 48 f urth'emaintain the watertight nature of the assembly, the washer 48 externallyand the washer 41 internally of the neck 52. An adjustable screw plug 6Iis threaded in the neck 52 for compressing washer 41.

The bottom frame member 36, Fig. 2, is circular in shape and secured toupper frame member 35 by bolts 55. It ts 'closely within the circularapron 31 of the meterhousing top II. Member 36 has a vertically risingsemicircular support portion 38A integral therewith and providing amounting arm 39 in which is mounted a bushing 4I. Bushing 4I receivesthe end t2 of the driving shaft I8 and the end 45 of the driven shaft44.

A tubular sleeve 46 threaded into the lower frame member 36 extendstherebeneath and provides support for-the bushing 54 about the shaft I8.It is headed at its lower end to engage a apertured sand ring cap 51 isheld to the bottom frame member 36 in any desired position of rotation.The sand ring cap is adjustable about the tubular sleeve 46 to presentnew bearing surfaces 5 to the lower end of the intermediate spindle 59which extends through bushing 56 in the bottom frame member 36/intothrust engagement with sand ring cap 51.

A sand ring chamber 40 tightly fitting Within l the cap 51, is mountedupon the top of chamber I to enclose the pawl I1 and thespindle discassembly I6.

. When the upper and lower meter units are assembled and it is desiredto lock the two to- 15 gether, a conventional clamping 'or locking means`is applied outside the device. When assembled, pressure of the meterhousing top I I will be communicated through the frame member 35 securedin the partition 50, the portion 38, lower frame 20 member 36, sand ringcap 51, and said ring wall 40 to the chamberA I5 positively forcing thechamber I 5 into position, not only to maintain the discharge opening 22in registry with the discharge 25 port I4 but to provide a bearingcontact with the movement of the bevelled ear 25 in the channel28.

In general the operation of parts in the metering device has not beenaffected by this invention except to insure a better and more prolongedoper- 39 ation. Water or any other liquid entering the registeringdevice by'way of port I3 must pass through the screen 30 before it canenter the disc chamber I5. The larger bits of sediment will be stoppedat the screen 30. Screens are not new in the art but positioning thisone as I have, by means of the arms 3I, is new, and I thus provide a newand advantageous organization for proper meter operation. f

As water passes about the chamber I5 it was 40 formerly free to depositthe finer sediments upon the open gear train assembly I9 and the spindleand disc assembly I6, thereby permitting abrasive and impeding. actionsas the case might be. My sand ring casing 40 tightly tted upon thecharn- 45 ber I5 and secured to the base member 36 now excludeslallsediment from entry to chamber I5- by way of spindle opening on topthereof. The tight tting annular fr'ame member 36 and the apron 31 ofthe meter housing top I I create a similar condition for the gear trainassembly I9. It is to be noted that all of my locking means are outsidethe flow of liquid. 'Ihe meter top Il is secured to the meter housingbottom I2 externally of the device. The lock nut 49 holding the upp"rframe member 35 in the partition 50 is in the register chamber and isthus out of the line of the liquid flow. With this new organizationthere is very little possibility of internal disorgani- Zation by theinadvertent release of any locking means through action of the liquid.Each part internally of the register is coactingin maintaining therelative position of each with the other due to the pressure actionwhich has been previously described.

Corrosive action which might tend to cause the .Capscrews 55 to stick,is minimized by the fact that such screws are located in the gearchamber. Likewise Vthe gears in said chamber are protected both fromcorrosive action and from foreign matter inasmuch as-said chamber isclosed from the meter proper by the partition disk 36 and the sleeve 31.While the joint at this point is not suiciently tight to exclude water,it does virtu- 'ally prevent any ow through the gear chamber, 75 thuseliminating any'renewal of the chemical side walls of the meter housingbottom I2 by the agencies in the water which, by renewal, might causecorrosion.
